IMPROVEMENT IN JELLV-GLASSES.

Specification forming part of Letters Patent No. 187,714, dated February27, 1877; application led December 18, 1876.

To all whom it may concern:

Be it lknown that I, WILLIAM C. KING, of Union township, county ofAllegheny, State of Pennsylvania, have invented or discovered a ne7 anduseful Improvementin Jelly-Glasses; and I do hereby declare thefollowing tO be a full, clear, concise, and exact description there# Iof, reference being had to the accompanying drawing, making a part ofthis specification, in Whichlike letters indicating like parts- Figure lis an elevation, slightly in perspective, of my improved jelly-glass andcap. Fig. 2 is a vertical sectional view thereof, and Fig. 3 is adetached sectional view of one edgeof the cap and of the packingring.

My present invention relates to the class of manufactures commonly knownunder the name of jellyglasses57 and consists of a pressed-glassreceiving-vessel made largest at its mouth and tapering gradually to itslower end, as in an ordinary jelly-glass, combined With a pressed-glasscap, an annular ange O11 which enters the mouth sufficiently' far for apackingiing, rectangular in cross-section, to be arranged cornerwise inan annular V- shaped recess On the outer face of the ange, and so thatan outwardly-'projecting corner shall engage the inner Wall of the mouthof thejellyglass.

rlhe jelly-glass B is made in the usual way, by pressing, and ofanydesired size. For some purposes I propose to make them much larger thanhas been usual. Its cavity is largest at its mouth. It is covered by acap, A, the rim of which rests on the mouth of the glass B. On the underside of the cap A is an annular iange, a, extending down far enough fora V-shaped groove, c, to be made in its outer periphery. In this grooveI arrange a packing'ring, e, of india-rubber or other suitable material,which is made rectangular .in cross-section, so that, with one of theangular corners occupying the bottom of the V-shaped groove c. thediagonally-opposite corner Will, when the cap is iu place, engage thecavity-Wall of the mouth of the glass B with a moderate degree oftightness, such as will hold the cap in place as against any tendency tobe or become loose in ordinary handling, and such as will exclude allinsects and vermin. It is also true that such a packing thus appliedwill, with lnost if not all -articles which such glasses are designed tohold, prevent loss by leakage, since, the glass B being pressed, greateruniformity can be secured in its manufacture than With hand-m ade orblown articles, from Which it follows that a packing-ring thus employedwill in all, or nearly all, cases, bear uniformly all around with thedesired degree of tightness.

A packi ng-ring cylindrical in cross-section, or of other equivalentform, may be substituted for that shown, and even a rectangular ring maybe arranged in a la't groove, so that its Outer .periphery shall bearagainst the sides of the mouth in like manner, and With a useful effect.

I claim herein as my invention- A jelly-glass consisting ofa taperingpressedglass vessel, B, having a mouth interiorly unreoessed, and apressed-glass cap, A, the latter having an exterior rim to rest on themouth of B, a flange, a, to go inside the mouth, With a groove orrecess, c, in the exterior periphery of the flange, to receive andretain a packing-ring, c, the article as a Whole being substantially asset forth.

In testimony whereof I have hereunto set my hand.
